Integrate external AuthZEN PDP authorization - #5224
Conversation
📝 WalkthroughWalkthroughThis change adds external AuthZEN PDP connections, persistence, CRUD APIs, declarative import/export, resource-server authorization-engine configuration, PDP evaluation routing, subject enrichment, and comprehensive unit and integration coverage. ChangesExternal AuthZEN PDP support
Estimated code review effort: 5 (Critical) | ~90+ minutes Merge Risk: 🟡 Moderate · up to Action discovery can use the wrong subject category, and declarative files can unexpectedly create PDP connections. These behaviors and the missing public documentation should be corrected before merge. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

In `@backend/internal/authz/engine/errors.go`:
- Line 24: Update IsInvalidRequestError to classify both InvalidRequestError
values and *InvalidRequestError pointers when passed directly or wrapped, using
compatible errors.As targets. Add a test covering a wrapped pointer-form error
while preserving existing value-form behavior.
In `@backend/internal/authz/init.go`:
- Around line 34-35: Update the ExternalAuthZEN startup validation near
dynamicExternalAuthZENRouter so enabled deployments with persisted runtime PDP
connection routes are allowed. Remove the static PDP-only rejection or validate
the combined static and runtime PDP sources, while retaining rejection only when
no PDP is available from either source.
In `@backend/internal/connection/authzenpdp/authzen_pdp_store_constants.go`:
- Around line 12-14: Update the AuthZEN PDP connection queries to persist and
retrieve TimeoutMS, RetryCount, and SubjectAttributeMappings consistently across
create, get, list, and update operations. Keep the column ordering and parameter
bindings aligned with the corresponding connection model fields and ensure
connectionModelFromAuthZENPDP receives the stored values instead of defaults.
In `@backend/internal/connection/authzenpdp/authzen_pdp.go`:
- Around line 323-335: Update NormalizedSubjectMapping and
AuthZENPDPRuntimeConfig to preserve subject attribute mappings grouped by
UserType instead of overwriting duplicate source attributes. During evaluation,
select the mapping group matching the actual user type before constructing PDP
subject data, while retaining existing behavior for non-duplicated mappings. Add
coverage with two user types mapping the same source attribute to different
pdpAttribute values and verify each selects its own mapping.
In `@backend/internal/connection/connection_declarative_model.go`:
- Line 50: Add a FailOpen bool field with the specified YAML and JSON tags to
connectionExportModel, then update connectionModelFromAuthZENPDP and
connectionModelToAuthZENPDP to copy FailOpen in both directions. Add coverage
confirming a true FailOpen value survives the declarative connection round trip.
In `@backend/internal/connection/mapping.go`:
- Line 109: Add ErrorConnectionHasBlockingDependencies.Code to the HTTP 409
error-mapping case alongside the existing dependency-related codes, so
deleteAuthZENPDP blocking-dependency failures return conflict status.
In `@backend/internal/system/config/config.go`:
- Around line 620-643: Update documentation for
backend/internal/system/config/config.go lines 620-643, covering
AuthorizationConfig, ExternalAuthZENConfig, and ExternalAuthZENPDPConfig fields
including enablement, PDP endpoints, timeout, retries, resource-server routing,

what is meant by type can u give me some example
There was a problem hiding this comment.
type selects which authorization engine a resource server should use.
Examples:
rbacmeans evaluate with ThunderID’s built-in authorization engine.external-authzen-pdpmeans send the AuthZEN evaluation request to the configured external PDP connection.

why we need special logic for AuthorizationEngine?
There was a problem hiding this comment.
This is only to avoid persisting an empty authorizationEngine object for normal resource servers.
authorizationEngine is optional and stored inside the existing PROPERTIES JSON column. We only add it to that JSON when either the engine type or external PDP connection id is configured. Otherwise existing resource servers keep the same properties shape as before.

so for each resource servers, rather than having a dedicated column for authoirzation servers, we are having it as json property, wont it make hard to query what resource/resource servers used by this authorization type

can we make this magic string as constnat and whats the purpose of this check
There was a problem hiding this comment.
Yes, we can move external_authzen_pdp to a constant.
The purpose of this check is to keep update behavior safe. If authorizationEngine.type is omitted, we preserve the existing resource-server engine config. If it is set to the supported external PDP engine type, we keep it. If any other value is provided, we clear the authorization engine config so an unsupported engine type is not persisted.

why we need not to pass the nill

Earlier the function accepted one argument, so we passed nil. But that argument was not used anywhere inside the function. Since the wrapper does not need any input now, I removed the unused parameter.

In `@backend/internal/authz/engine/external_authzen_pdp_test.go`:
- Around line 330-334: Protect the shared attempts counter used by the
newAuthZENTestServer handler and the later test assertion with a mutex. Lock
around both the increment in the HTTP handler and the read near the assertion,
ensuring the expected attempt count remains unchanged while eliminating the data
race.
In `@backend/internal/authz/engine/external_authzen_pdp.go`:
- Line 236: In backend/internal/authz/engine/external_authzen_pdp.go, mask
sensitive PDP data before logging: at lines 236 and 273 use log.MaskedMap for
response contexts, at line 318 use log.MaskedString for resource_id, and at line
347 use maskedAuditString for the batch audit resource ID. Update the relevant
batch and single-response logging paths while continuing to use
internal/system/log.
- Around line 452-453: Update toAuthZENEvaluationRequest so authZENResource.Type
and authZENResource.ID are populated from the provided resource-server identity,
including the ResourceServer.ID-only case; ensure standard evaluations never
send empty required resource.type or resource.id fields.
In `@backend/internal/authz/service.go`:
- Around line 120-132: Update the resolution caching in the evaluation flow
around resolvedExternalEngines and resolveEngine to track whether each
resourceServerKey has already been resolved in a separate resolved map. Cache
both successful external-engine resolutions and negative results where ok is
false, and consult the resolution-state map before calling resolveEngine so
repeated evaluations avoid duplicate lookups.
- Around line 307-310: Update enrichRequest around the userService.GetUser call
to continue without user enrichment when the error is userpkg.ErrorUserNotFound,
allowing the batch to produce a decision for that subject; preserve the existing
tidcommon.InternalServerError return for all other errors.
In `@backend/internal/connection/authzenpdp/authzen_pdp_store.go`:
- Around line 158-160: Update the RetryCount defaulting condition in the
connection normalization logic to treat all non-positive values like TimeoutMS:
assign DefaultRetryCount when RetryCount is less than or equal to zero,
including values loaded through the declarative store path.
In `@backend/internal/connection/authzenpdp/authzen_pdp.go`:
- Around line 244-251: Update ValidateEndpoint to accept only http and https
schemes, while continuing to require a non-empty host and absolute URL; reject
all other schemes with the existing validation error.
In `@backend/internal/resource/declarative_resource.go`:
- Around line 94-102: Update the documentation under docs/ to cover the new
AuthZEN configuration and connection APIs, including authorizationEngine,
external_authzen_pdp, and externalPDPConnectionId in declarative and REST
schemas; document external PDP setup, endpoints, authentication, retries,
subject mappings, fallback behavior, connection lifecycle and deletion
restrictions, and OAuth client-credentials/refresh-token authorization outcomes
for evaluation, denial, PDP failures, and fallback.
In `@backend/internal/resource/service.go`:
- Around line 449-450: Document the public AuthZEN PDP resource-server and
connection APIs by updating the API references for authorizationEngine,
external_authzen_pdp, externalPDPConnectionId, the /connections/authzen-pdp
routes, and all connection fields; add a guide covering external PDP routing,
missing-connection fallback, fail-open behavior, and resource-server update
semantics. Use the AuthorizationEngine and
AuthorizationEngineTypeExternalAuthZENPDP behavior in the service implementation
as the source of truth.
- Around line 447-452: Update validateResourceServerUpdate to reject any
non-empty AuthorizationEngine.Type other than
providers.AuthorizationEngineTypeExternalAuthZENPDP before the normalization
logic runs. Return an appropriate validation error instead of clearing and
persisting the unsupported configuration; preserve inheritance for an empty type
and acceptance of the supported external PDP type.
In `@backend/pkg/thunderidengine/providers/model.go`:
- Around line 202-223: Update the authoritative API specification in
api/connections.yaml with the external-authzen-pdp connection endpoints and
schemas, then document its configuration and lifecycle behavior in the relevant
docs/content/guides guide. Also document the resource-server
AuthorizationEngineConfig fields authorizationEngine.type and
authorizationEngine.properties.externalPDPConnectionId, including their expected
usage.
In `@tests/integration/authzen/external_authzen_pdp_test.go`:
- Line 119: Replace the s.Require().NoError assertion inside the httptest
handler with error capture, then assert the captured error from the main test
goroutine after the request completes. Apply the same change to the other
handler occurrence, ensuring any shared error state is synchronized or safely
communicated before the test assertion.
- Around line 552-556: In the request flow around testutils.GetHTTPClient().Do,
check err with s.Require().NoError immediately after the call, before accessing
response.Body or reading it. Preserve the existing response-body read, close,
and readErr assertion for successful requests.

declarative checks are handled in connection/service.go using CheckDeclarativeCreate, CheckDeclarativeUpdate, and CheckDeclarativeDelete guards.

What is the use of having these separate maps for external and resolved engine evaluation?

These maps separate evaluations by resolved engine so external PDP requests can be batched while preserving the original evaluation order. The index map is needed to merge PDP results back into the complete response, and the fail-open map keeps the connection-specific fallback behavior

- If both are needed can't we resolve it from the ID?

Resolve every SearchActions subject.
When request.Subject.Type is non-empty, this branch skips resolveSubject. A caller can provide a valid user ID with a different type, such as admin. The request then reaches the authorization provider with the wrong entity category and can return actions for that category.
Resolve the subject unconditionally, as EvaluateAccess does. Add a regression test for a supplied type that differs from the entity category.
Proposed fix
- if strings.TrimSpace(request.Subject.Type) == "" {
- resolvedSubject, svcErr := s.resolveSubject(ctx, request.Subject)
- if svcErr != nil {
- return nil, svcErr
- }
- request.Subject = resolvedSubject

Document the complete AuthZEN PDP feature
This PR adds public REST, configuration, authorization-routing, and declarative-import behavior. Add one consolidated documentation update before merging.
Missing documentation:
- External AuthZEN PDP connections: document the CRUD and
/usagesendpoints, all connection fields, absolute endpoint requirements, timeout and retry defaults, subject mappings,failOpenbehavior, validation failures, and delete blocking dependencies. - Resource-server authorization: document
authorizationEngine.type,externalPDPConnectionID, routing by resource-server identifier or ID, subject resolution and attribute enrichment,subject.idandsubject.type,resource.typeandresource.id, and external PDP failure behavior. - Declarative AuthZEN connections: document the
type: external-authzen-pdpYAML schema, create behavior, ID-based upsert behavior, anddryRunresults without persistence.
Update the relevant guides and the authoritative OpenAPI sources, including docs/content/guides/protocols/authzen/pdp.mdx, docs/content/guides/declarative-configurations/import-resources.mdx, api/connections.yaml, api/resource.yaml, and api/import.yaml. Do not add per-endpoint text manually to docs/content/apis.mdx.

Gate AuthZEN PDP declarative creation on global declarative mode.
When idp.ShouldLoadDeclarativeIDPResources() is true while declarativeresource.IsDeclarativeModeEnabled() is false, loadDeclarativeResources still dispatches AuthZEN PDP documents. This branch calls authZENPDPStore.create, which persists the connection through the configuration database. Add the global declarative-mode gate before creating the AuthZEN PDP connection.
